“In their experiments, the researchers compared mice given the ketogenic diet to mice fed a normal diet and to those injected with BHB. Compared with their untreated counterparts, both groups of treated mice grew more new brain cells in an area called the granule cell layer of the dentate gyrus, which is associated with the ability to learn and form new memories. ”
